1 snnetrrcn'rron forming ma of Letters Patent No. l118,421, astenDecember 31, 1889. A `Application meenam 9, 1889, Senn nemesio. (Noman.)

To all whom it may concern.'

Be it known that I, WILLIAM OsBoRN, a citizen of the United States,residing atDuluth, in the county of St. Louis and State of Minnesota,have invented certain new and useful Improvements in Devices for Conveylthe following to be a full, clear, and exact description of theinvention', such as will enable others skilled in the art to which itappertains p to make and use the same.

YMy invention relates to a device for conveying sand or any substancethat will iiow with its own gravity; andithas for its object to'providea simple and cheap 'Wayof unloading a scow.

My invention further consists inthe poen-- liar construction andarrangement of parts, as will hereinafter be fully explained, andparticularly pointed ont in the claims, reference being had to theaccompanying drawings, in Whichf' y Figure l is a longitudinal section.vFig. 2 ,is a cross-section taken on line C C, Fig. l; and Figs. 3 and 4are detail views of the valve. v

S is a scow, having on the inside, near the bottom and paralleltherewith, a pipe P, of

' any desired size, extending from one end of it tothe other. Said pipeis so constructed that the end of it near the stern is passed throughthe bottom of the scow, thereby 1 coming in contact with the waterbelow, as

' i taehed to a suction-pump. New, the body atl B, and the other endinclined upward and Vthrough the deck of thel scow, as .at A, theportion above the deck designed to be atportitn ofV the scow isdividedinto comparu aI pump I do not confine myself/ro onlyr three hop:

pers in the scow, for there could be any 'Idesired number.A l

The ,operation ot my ldevice is as followsi supposing the hoppers to befull of sand and attached at A, itis set inlmotion,A

which causes'a iowot Water through the pipe P, entering at'B, anddischarging at the pump. New, to remove the sand from the hoppers say anequal amount from each yhopper-#partly open the valve offe'ach one,

which will allow the sand to iiow'through and v unite with the streaminthe pipe, and. thereby `be carried to and discharged at the ,out let.It will also be seen that onehopper at a timemaybe discharged With thesame facility.

From the` foregoing description,` taken in connection with the drawings,the operation and advantages of my improvement will read ily beunderstood.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is*

l. The combination, with the mud or sand hopper having a valved outletin its bottom through which the material falls by gravity, of asuctionpipennder the hopper and `into which its outlet opens, said pipebeing open at one end for the entrance of water and open at its oppositeend for the discharge of the water .uid material from the hopper,substantially as set forth.

2. The combination, with a scow having compartments therein communicating with a suction-pipe'located just below the compartments invthe bottom portion of the soon', of valves connectingsaid compartmentsand pipe, vsaid pipe open at 4both ends and communicating at one endwith 'the water below the scow, substantially as and for the purpose setforth. g

In testimony whereof I affix mysignatnrc in presence of two witnesses,

WILLIAM osnonn.4
